- I am tempted to say "Because it does not", but that would be a bit
- premature. Proving a zero is one of the hardest jobs in physics,
- right up there with measuring a very small, yet non-zero, quantity.
- Both are dominated by systematic errors rather than statistical errors,
- so that more data does not always improve the situation. Only more
- careful experiments will clarify what is going on.
-
- The real reason is that the purported positive experiments are not
- reproducible. The negative ones are, but they can always be dismissed
- on the basis that some (unspecified, because it is unknown) condition
- was not met. The biggest symptom of this problem is that the very
- *definition* of the phenomena being sought is still changing. It is
- hard to do a test when one person says light water gives nothing and
- someone else says light water is the way to go.
-
- We do not yet have a recipe, where you can be told "do this and you
- get heat, change this one variable and it will go away" and then
- proceed to monitor other things like nuclear products. The contrast
- with high-Tc superconductors, where everyone was making them within
- a week of word getting out, should enlighten you.

-
- I note with interest that you do not include scientific journals in
- your list of things you have read. The information there is quite
- thin, and then only if your library happens to get the rather obscure
- journal where most of it appears.

-
- Yes. More so in some fields (particle theory was famous for this)
- than others, but it is not uncommon to see rather emotional responses
- to a challenge to accepted ways. Not-invented-here. Turf battles.
- I once had my head almost bitten off when I (a theorist!) suggested that
- the reason certain data seemed unusual was that they had most likely
- made an error in background subtraction (they had followed a procedure
- quite different from that used by others). Yo Mama! Its our background
- and we can subtract it any way we like, and besides, it has already been
- published in a respected journal so it must be right!
-
- I love meetings.
